UNI20+PH+ORP PH Probe ORP Sensor with Dual Channels Transmitter

UNI20 Water meter could be with one channel or dual channels for your choice, UNI-20 Water quality meter is stable, and also with recorder for your choice.
PH ORP SENSRS

Quantity:
  • UNI20+PH+EC
  • PROBEST
  • 90268090

UNI20 Water meter could be with one channel or dual channels for your choice, UNI-20 Water quality meter is stable, and also with recorder for your choice. 

The UNI-20 transmitter is highly versatile, and the existing digital and analog sensors from the company can be freely connected. Measurable parameters include pH, DO, ORP, Conductivity, Turbidity, SS, Chlorophyll, Blue-green algae, Residual chlorine, UVCOD, Ionic ammonia nitrogen, Nitrate nitrogen, Transparency and other parameters. UNI-20 can also choose single channel or dual channel configuration according to requirements. One transmitter can connect up to two sensors, reducing transmitter cost and installation space.

Measurement Principle:

PPH-500 pH sensor is a combination electrode combined precious metals indicator electrode with reference electrode. Firstly measure the potential difference of working battery made up of measuring electrode and reference electrode in the solution,then use linear relation of pH value of the measuring solution and potential of working battery to realize the on-line monitoring.


Features:

1. Good repeatability and stablity. Suitable for fresh water and sea water testing, PH 0-14pH.  

2. Simple cleaning and activation,quite high balance speed.The function of automatic temperature compensation.

3. Optional analog-digital conversion module to achieve digital signal output,high anti-jamming capacity and far transmission distance.

4. Quick and easy field installation,plug and play.


Applications:

1. PH online monitoring in technological process of inlet/outlet of sewage treatment plant,sedimentation basin and biochemical reaction basin and so on.

2. PH online monitoring of municipal water supply industry,surface water and aquaculture and so on.

3. PH online monitoring of industrial process water and in waste water treatment process.
